Drill bit for metal Art-Pol AR52024, cobalt, cylindrical shank, 2.4 mm

Art-Pol AR52024 cobalt drill bit, 2.4 mm diameter with a cylindrical shank, is designed for precise drilling in hard metals and metal alloys. The cobalt-enriched composition improves heat resistance and prolongs cutting edge life compared with standard high-speed steel bits. Its small diameter and rigid geometry make it suitable for creating accurate holes in steel, stainless steel and similar materials when used in hand drills or drill presses.

Advantages

The cobalt material provides higher red-hardness and better wear resistance at elevated temperatures, reducing the need for frequent re-sharpening. The cylindrical shank ensures secure clamping in standard chucks, and the compact 2.4 mm diameter allows for fine, accurate hole placement. The bit’s geometry supports stable drilling performance in tough alloys and reduces drill wandering on hard surfaces.

Suitable for

• Drilling small-diameter holes in steel and stainless steel
• Working with hard metal alloys and heat-treated parts
• Use in hand drills and drill presses for precision tasks
• Manufacturing, maintenance, and repair applications requiring fine holes

Key specifications

• Material: cobalt-enhanced high-speed steel
• Diameter: 2.4 mm
• Shank type: cylindrical (round) shank for standard chucks
• Intended material: steel, stainless steel, hard alloys
• Typical use: drilling with hand drills and drill presses

How to use

Secure the drill bit in the chuck ensuring it is centered and firmly tightened. Select a suitable cutting speed and apply steady, moderate feed pressure; slower speeds are recommended for stainless steel and hard alloys to avoid overheating. Use cutting fluid or coolant when drilling tougher materials to extend tool life and improve chip evacuation. Withdraw the bit periodically to clear chips when drilling deeper holes.

Usage recommendations

For best results, pre-center the hole with a spotting drill or center punch when accuracy is critical. Maintain appropriate coolant flow and reduce speed under heavy load to preserve the cobalt cutting edge. Store the bit in a dry case to prevent corrosion and protect the cutting tip.
